A delivery pipe 8 is fixedly installed at the bottom of the storage tank 1, and a water pipe 9 is fixedly installed on the inner top wall of the storage tank 1. The water pipe 9 is connected to an external water pump through a pipeline. Several nozzles 10 are provided on the water pipe 9. The water pipe 9 is arranged in a ring structure. The several nozzles 10 are distributed on the water pipe 9 with equal rounded corners. The several nozzles 10 with equal rounded corners can spray a large area inside the storage tank 1, thereby improving the cleaning effect inside the storage tank 1. A support plate 11 is fixedly installed on the right side of the support frame 2. A metering cylinder 12 is fixedly inserted through the support plate 11. A replenishment pipe 13 is fixedly installed at the bottom of the metering cylinder 12. Both the delivery pipe 8 and the replenishment pipe 13 are equipped with check valves 14. A metering delivery mechanism 15 connected to the metering cylinder 12 is provided on the support plate 11. A metering adjustment mechanism 16 is provided on the metering delivery mechanism 15. Two reinforcing ribs 20 are fixedly installed at the bottom of the support plate 11 and are fixedly connected to the support frame 2. The reinforcing ribs 20 can improve the structural strength of the connection between the support plate 11 and the support frame 2, thereby improving the load-bearing capacity of the support plate 11. The quantitative conveying mechanism 15 includes: The second motor 15-1 is fixedly mounted on the upper part of the support plate 11. A rotating disk 15-2 is fixedly mounted on the output shaft of the second motor 15-1. A connecting rod 15-3 is rotatably connected to the front side of the rotating disk 15-2. A lifting frame 15-4 is hinged to the upper end of the connecting rod 15-3. A fixed rail 18 is fixedly mounted on the upper part of the support plate 11 at the front side of the metering cylinder 12. A slider 19 is slidably mounted on the fixed rail 18. The slider 19 is fixedly connected to the lifting frame 15-4. Through the cooperation of the fixed rail 18 and the slider 19, auxiliary guidance can be provided for the up and down movement of the lifting frame 15-4, thereby improving the movement stability of the lifting frame 15-4, the lifting rod 15-5 and the piston 15-6. The lifting rod 15-5 is movably inserted into the metering cylinder 12. The upper end of the lifting rod 15-5 is fixedly connected to the lifting frame 15-4. The lower end of the lifting rod 15-5 is fixedly provided with a piston 15-6, and the piston 15-6 is movably abutting against the metering cylinder 12. The quantitative adjustment mechanism 16 includes: The No. 3 motor 16-1 is fixedly installed at the bottom of the rotating disk 15-2. A threaded rod 16-2 is fixedly installed on the output shaft of the No. 3 motor 16-1. The threaded rod 16-2 is rotatably installed in the movable groove 17 opened on the front side wall of the rotating disk 15-2 through a bearing. The movable block 16-4 is movably disposed in the movable groove 17. The movable block 16-4 is screwed onto the threaded rod 16-2. The movable block 16-4 is rotatably connected to the connecting rod 15-3 through the rotating shaft 16-3. The distance between the connecting rod 15-3 and the center of the rotating disk 15-2 can be adjusted by the quantitative adjustment mechanism 16. This changes the reciprocating stroke of the lifting rod 15-5 and the piston 15-6 when the rotating disk 15-2 rotates, thereby realizing the adjustment of the single fluid replenishment dose.

[0018] When using this invention, the detergent is stored in the storage tank 1, and the replenishment pipe 13 is connected to the liquid supply pipe inside the dishwasher. When it is necessary to replenish the detergent in a measured amount during the operation of the dishwasher, the second motor 15-1 can be started. The second motor 15-1 drives the rotating disk 15-2 to rotate one revolution. During this process, the connecting rod 15-3 will drive the lifting frame 15-4 to move up and down. The lifting frame 15-4 drives the piston 15-6 to move up and down inside the metering cylinder 12 through the lifting rod 15-5. When the piston 15-6 moves upward, a negative pressure is formed inside the metering cylinder 12, and the detergent in the storage tank 1 is sucked into the metering cylinder 12 through the delivery pipe 8. When the 6 moves downward, the detergent in the metering cylinder 12 can be discharged through the replenishment pipe 13, thereby achieving metered replenishment of detergent for the dishwasher. If it is necessary to change the amount of detergent replenishment, the No. 3 motor 16-1 can be started. The No. 3 motor 16-1 drives the threaded rod 16-2 to rotate, adjusting the position of the movable block 16-4 in the movable slot 17. The movable block 16-4 drives the connecting rod 15-3 to move, adjusting the distance between the end of the connecting rod 15-3 and the center of the rotating disk 15-2, changing the up and down movement of the lifting frame 15-4, the lifting rod 15-5 and the piston 15-6 when the rotating disk 15-2 rotates, thereby adjusting the amount of detergent replenishment per cycle. When cleaning is required inside the storage tank 1 and the metering cylinder 12, disconnect the replenishment pipe 13 from the dishwasher pipe, then use an external water pump to deliver water to the water pipe 9, and spray the water into the storage tank 1 through the nozzle 10. At the same time, start the first motor 3, which drives the rotating rod 4 to rotate. The rotating rod 4 drives the turbine 5 and the connecting frame 6 to rotate. The connecting frame 6 drives the scraper 7 to rotate inside the storage tank 1. The scraper 7 can scrape off the detergent and other substances attached to the inner wall of the storage tank 1. The turbulence generated by the rotation of the turbine 5 is used to clean the inside of the storage tank 1. Afterwards, the second motor 15-1 can be started, and the piston 15-6 can be moved up and down in the metering cylinder 12 by the cooperation of the rotating disk 15-2, the connecting rod 15-3, the lifting frame 15-4 and the lifting rod 15-5. This not only draws the water in the storage tank 1 into the metering cylinder 12 and discharges it through the replenishment pipe 13, but also cleans the inside of the metering cylinder 12.

[0019] Compared with the prior art, the beneficial effects of this utility model are: Through the synergistic effect of the turbine 5 rotation and the scraper 7, combined with the annular spray, a triple cleaning mechanism of "mechanical scraping - fluid flushing - turbulent cleaning" is formed to achieve efficient cleaning of the inside of the storage tank 1 and avoid adverse phenomena such as detergent sticking to the wall in the storage tank 1. With the cooperation of the quantitative adjustment mechanism 16, the stroke of the piston 15-6 can be precisely adjusted to achieve stepless adjustment of the single replenishment volume, meeting the dynamic dosage requirements of different washing programs. The fixed rail 18 and the slider 19 can provide auxiliary guidance for the up and down movement of the lifting frame 15-4, thereby improving the movement stability of the lifting frame 15-4, the lifting rod 15-5 and the piston 15-6. The reinforcing rib 20 can improve the structural strength of the connection between the support plate 11 and the support frame 2, thereby improving the load-bearing capacity of the support plate 11.

[0020] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
